Two W7's? You're going to need some way to turn those suckers down. But then, you <i>really<i/> don't need the seperate front and back RCAs as long as you don't constantly feel the need to adjust the fading from rear to front. If it was me, I wouldn't want a seccond thing in my dash if I could avoid it, just because it doesn't look as good, and the A/D/A conversion can't be a good thing. (I actualy have a 2nd HU for a tuner, but that's not really by choice)
